Abstract
The insulation booth device of the utility model outdoor vacuum circuit breaker is assemblied in insulation booth (7) by primary conductive loop (8) to assemble, galvanic circle is in series successively by conducting rod (1), three hole conducting blocks (2), be flexible coupling (3), connecting lever (4), vacuum interrupter (5), four hole conducting blocks (6) dimly, and these current-carrying parts are all contained in insulation booth (7); The insulation booth device of this outdoor vacuum circuit breaker, guarantees that the inner all bands of vacuum circuit-breaker lead part under any state, is all sealed in the profile of insulation booth (7) cavity, effectively avoids the electric discharge arcing fault between three-phase.
Description
Technical field
The utility model is in particular to a kind of insulation booth device of outdoor vacuum circuit breaker.
Background technology
Existing outdoor vacuum circuit breaker internal structure is mainly composed in series by the outlet of line side terminal and the insulation booth assembled, and is then connected in sequence by conducting rod (1), three hole conducting blocks (2), vacuum interrupter (5), be flexible coupling (3), connecting lever (4) in the insulation booth device assembled.Because insulation booth (7) Sidewall Height is lower, there is the naked leakage of part outside at insulation booth (7) after electrified body connecting lever (4) assembling, alternate electric discharge can be caused, three alternate arcing faults easily occur; And the industrial frequency withstand voltage in short-term of circuit breaker is filling SF
6just 42kV/min can be reached when insulating gas.
Utility model content
The utility model object designs a kind of insulation booth device of outdoor vacuum circuit breaker.
The insulation booth device characteristic of the utility model outdoor vacuum circuit breaker is: the inner primary conductive loop (8) of vacuum circuit-breaker is in series successively by conducting rod (1), three hole conducting blocks (2), be flexible coupling (3), connecting lever (4), vacuum interrupter (5), four hole conducting blocks (6), and primary conductive loop is assemblied in insulation booth (7), and the electrified body connecting lever (4) in primary conductive loop (8) is all inner at insulation booth after assembling.
The insulation booth device of this outdoor vacuum circuit breaker, increase its insulation booth (7) Sidewall Height, guarantee that all bands of circuit breaker internal lead part under any state, all be sealed in the profile of insulation booth (7) cavity, and the insulation booth increased (7) sidewall forms insulation between connecting lever (4) and contiguous current-carrying part to be covered, and effectively avoids the electric discharge arcing fault between three-phase; And the industrial frequency withstand voltage in short-term of circuit breaker is not filling SF
6just can reach 42kV/min when insulating gas, fill SF
6when insulating gas, then 48kV/min can be reached.Namely the insulation booth device of this vacuum circuit-breaker not only can make circuit breaker insulation distance increase, and insulation property improve; And the arcing fault that can effectively avoid between three-phase.
Accompanying drawing explanation
Fig. 1 is existing outdoor vacuum circuit breaker internal structure schematic diagram;
Fig. 2 is the utility model outdoor vacuum circuit breaker insulation booth device profile and internal structure schematic diagram;
Fig. 3 is primary conductive loop structure schematic diagram.
Embodiment
In figure: 1, conducting rod 2, three hole conducting block 3, be flexible coupling 4, connecting lever 5, vacuum interrupter 6, four hole conducting block 7, insulation booth 8, primary conductive loop
As shown in the figure, the primary conductive loop, inside (8) of the utility model outdoor vacuum circuit breaker is in series successively by conducting rod (1), three hole conducting blocks (2), be flexible coupling (3), connecting lever (4), vacuum interrupter (5), four hole conducting blocks (6), and these conduction parts are all contained in insulation booth (7).
The insulation booth device of this outdoor vacuum circuit breaker, increase its built-in electrical insulation box (7) Sidewall Height, guarantee that the inner all bands of vacuum circuit-breaker lead part under any state, all be sealed in the profile of insulation booth (7) cavity, and the insulation booth increased (7) sidewall forms insulation between connecting lever and contiguous current-carrying part to be covered, and effectively avoids the electric discharge arcing fault between three-phase; And the industrial frequency withstand voltage in short-term of circuit breaker is not filling SF
6just 42kV/min can be reached when insulating gas; Be full of SF
6when insulating gas, then 48kV/min can be reached.I.e. the increasing insulation booth device circuit breaker insulation distance not only can be made to increase of this vacuum circuit-breaker, insulation property improve, and effectively can avoid the arcing fault between three-phase.
During assembling, first assemble the inner primary conductive loop (8) of vacuum circuit-breaker insulated box device, namely conducting rod (1), three hole conducting blocks (2), be flexible coupling (3), connecting lever (4), vacuum interrupter (5), four hole conducting blocks (6) assemble successively, and are fixed in insulation booth (7); The assembling of this device is simple, easy for installation.
Claims (1)
1. an insulation booth device for outdoor vacuum circuit breaker, after it is characterized in that primary conductive loop (8) is assemblied in insulation booth (7) inside, the electrified body connecting lever (4) in primary conductive loop (8) is all inner at insulation booth.
